(01. 261-121) This invention relates to apparatus for diffusing by the numeral I8, is secured to the lower end of a fluid into another fluid, more especially to apthe pipe l1. Obviously the positions of the difparatus for difiusing ammonia into bulked latex. fuser head and the paddle arms l3 are correlated In the rubber industry, considerable quantities so that they do not interfere with each other.

This material has a tendency to become disks l9 and 20, which have fiat portions 2! at sour, and finally to coagulate or solidify. That is, their outer edges.

A periphery of the disks and the fluid is distributed difiuser head of the invention, generally indicated through the material in the tank over a rela- 55 tively large area whereby no concentration of the diifused fluid will exist adjacent the diffusion head. Thus the complete distribution of the diffused material through the fluid in the tank by the paddle arms I3 is simplified. A further feature of the invention is that the diffuser head is adapted to prevent the fluid II from flowing, or backing into the difiuser head. This may be due to the small area of the disks, immediately adjacent the edges from which the material is diifused, exposed to the fluid. The above property of the apparatus is particularly desirable when ammonia is diffused into latex as any latex hacking into the diffusion head coagulates and clogs the apparatus. Note that the invention provides a simple, easily controlled apparatus by which a desired amount of a substance, such as ammonia, can readily be obtained in a bulked fluid, such as latex. This greatly simplifie and facilitates the storage of same and is a desirable contribution to the art.

While a written description and illustration of one embodiment of the invention is disclosed protruding from both sides thereof, said threaded means engaging with said threaded member to secure said disks together and form a chamber therebetween.

2. An ammonia diffusion head comprising two similar thin-Walled concave disks, a pipe secured to and extending from both sides of one of said disks, a threaded collar secured to the end of said pipe adjacent the concave side of the one of said disks to which it is secured, a bolt carried by the remaining one of said disks and protruding from both sides thereof to engage with said threaded collar to secure said disks together and form a chamber therebetween, and means engaging with the outer end of said pipe to feed a fluid to said chamber whereby sufficient pressure on the fluid will force it out from between the abutted edges of said disks.

3. An ammonia diffusion head comprising two identical thin concave disks, a pipe secured to and and extending from both sides of one of said disks, a threaded collar secured to the end of said pipe adjacent the concave side of the one of said disks to which it is secured, a bolt carried by the remaining one of said disks and protruding from both sides thereof, said bolt being constructed and arranged to engage with said threaded collar to secure said disks together and form a chamber therebetween, the edges of said disks being urged into abutting relationship by said bolt, and means engaging with the outer end of said pipe to feed a fluid to said chamber whereby suiiicient pressure upon the fluid will force it therefrom between the abutted edges of said disks.
